PAPER-CLAIVI P.

SPECIFICATION forming part of Letters Patent No. 673,941, dated May 14:, 1901.

Application filed March 18,1901. Serial No. 51,747. (No model.)

To all whom, it may concern:

Be it known that we, HENRY D. BELLAS and RUSSELL 0. KING, citizens of the United States, residing at Apollo, in the county of Armstrong and State of Pennsylvania, have invented a new and useful Paper-Clamp, of which the following is a specification.

This invention relates to paperclamps for holding photographic or other paper securely while being cut to special form, the object of the invention being to provide a construc-.

tion wherein the form-plate to which the paper is cut is held firmly upon the paper to clamp it against a base board or plate, a further object of the invention being to provide for releasing the paper after the cutting operation, other objects and advantages of the invention being apparent from the following description.

In the drawings forming a portion of this specification, and in which like numerals of reference indicate similar parts in both views, Figure 1 is a perspective view showing the complete clamp, having its base formed by a table-top. Fig. 2 is a central longitudinal section of the clamp.

Referring now to the drawings, the clamp is shown as mounted upon a base, which in the present instance is the top 5 of a table, said clamp including a fixed member 6 and a hinged or clamping member 8, the member 6 i being secured to the base in any suitable manner to hold it securely. The member 6 in the present instance is substantially triangular in form and in the base thereof is formed a slot '7, the upper face of the member being cutaway to form ears 9 and 10, through which are formed transversely-alining perforations to receive a pintle or pivot-pin 11. The second member or engaging member consists of a body portion having a transversely-perforated ear 12 projecting from one end thereof and adapted to lie between the ears 9 and 10 with its perforation in alinement with the perforations of said ears to receive the pintle 11, so that the member 8 is hinged to the member 6 for movement in a vertical plane. At the opposite end of the member 8 from the ear 12 thereof are parallel arms 13, of which the body portion forms a connecting-web and the inner faces of these arms and of the body portion are beveled,- as shown.

The form-plate used in this apparatus is provided with an opening of the shape to which the paper is to be cut, and this shape may of course be whatever desired. In the present instance there is shown a form-plate 15, in which is an elliptical opening 16, and this plate is disposed against the under side of the member 8, so that the opening lies between the clamping arms of the member, and to hold the plate in position with respect to the member 8 spring-clips 17 are secured to the upper face of the plate and in position to rest upon the beveled faces, and thus prevent dropping of the plate from the member 8 when the latter is raised. These clips have sufficient frictional engagement to prevent sliding of the plate longitudinally from the member 8.. With this construction it will be seen that if a sheet of paper is properly placed upon the table or base the member 8 may be swung downwardly to lie with the form-plate upon the paper and if the member 8 be held firmly in lowered position it will hold the form-plate closely upon the paper, so that the paper may be cut with the usual form of cutting device run over the paper and following the line of the opening in the plate. I

To raise and lower the holding member and to hold it in lowered or operative position, the body portion of said member has an opening 18 therethrough, and passed through this opening is a headed rod or bar 19, the head of which rests upon the web, while the lower end of the rod extends through a slot 20 in the table 5 and has the lower end thereof turned laterally to form a pedal 21 to receive the foot of the operator. If then the lower end of this rod be swung to inclined position, the holding member will be raised pivotally to permit of insertion of the paper thereunder, while if the rod be swung in an opposite direction the holding member will be swung downwardly and into operative position and may be held firmly against upward movement.

It will be understood thatin practice a formplate having any style of opening may be used and that modifications of the specific construction shown may be made andthat any suitable materials and proportions may be used for the various parts without departing from the spirit of the invention.

What is claimed is 1. A device of the class described comprising hinged members one of which is adapted for attachment to a base and the other of which is provided with holding-arms having their inner faces beveled, and a form-plate having clips spaced inwardly from the edges thereof, said form-plate being adapted to lie against the under faces of the arms and with its clipsin engagement with the beveled faces thereof.

2. A device of the class described comprising hinged members one of which is adapted for attachment to a suitable base and the other of which includes spaced holding-arms and a connecting-web, the inner faces of the arms and web being beveled, and a formplate adapted to lie against the under faces of the arms and web and having clips for engagement with the beveled faces to hold the plate against displacement.

. 3. A device of the class described comprising hinged members one of which is adapted for attachment to abase and the other of which includes spaced holding-arms and a connecting-web, said arms and web having their inner faces beveled, a form-plate having clips for engagement with the beveled faces to hold the plate in position, and a bar attached to the web and having a pedal at its lower end for swinging the holding member.

4. A device of the class described comprising hinged members one of which is adapted for attachment to a support and the other of which includes spaced holding-arms and a connecting-web, the arms and web having their inner faces beveled for engagement by holding-clips of a form-plate, and a foot-operated device connected with the web for moving the second member.

In testimony that we claim the foregoing as our own we have hereto affixed our signatures in the presence of two witnesses.
